Signal Name
Description
1
EXT R/V CONT
For controlling CC, CR, CP, and CV modes through external voltage.
Voltage Control
External input voltages in the range of 0 V to 10 V correspond to 0 % to 100 % of the rated
current (CC mode), rated power (CP mode), or rated voltage (CV mode). In CR mode,
external input voltages in the range of 0 V to 10 V correspond to the range of resistances
from the maximum resistance to the minimum resistance.
Resistance Control
External resistances in the range of 0
Ω
to 10 k
Ω
correspond to 0 % to 100 % or 100 % to 0
% of the rated current (CC mode), rated power (CP mode), or rated voltage (CV mode). In
CR mode, external resistances in the range of 0
Ω
to 10 k
Ω
correspond to the range of
resistances from the maximum resistance to the minimum resistance or from the minimum
resistance to the maximum resistance.
2
IMON
Current monitor output. 10 V for full scale (H/L range), 1 V for full scale (M range)
3
A COM
Connected to the negative load input terminal on the rear panel.
4
V MON
Voltage monitor output. 10 V for full scale
5
EXT V CONT CV
For controlling CV mode through external voltage. External input voltages in the range of 0 V
to 10 V correspond to 0 % to 100 % of the rated voltage.
6
A COM
Connected to the negative load input terminal on the rear panel.
7
LOAD ON/OFF CONT
The load is turned on by a low (or high) CMOS level signal. The logic levels can be switched.
The internal circuit is pulled up to 5 V by a 10 k
Ω
resistor.
8
RANGE CONT 1
Input for switching the range externally.
1
The internal circuit is pulled up to 5 V by a 10 k
Ω
resistor. Valid only when the front panel setting is H range.
9
RANGE CONT 0
10
ALARM INPUT
The alarm is activated by a low CMOS level signal. The internal circuit is pulled up to 5 V by a
10 k
Ω
resistor.
11
TRIG INPUT
Unpauses the PLZ-4WH if a low CMOS level signal is applied for 10 µs or more. The internal
circuit is pulled up to 5 V by a 10 k
Ω
resistor.
12
A COM
Connected to the negative load input terminal on the rear panel.
13
LOAD ON STATUS
Turns on when the load is on. Open collector output by a photocoupler.
2
14
RANGE STATUS 1
Range status output.
3
Open collector output by a photocoupler.
15
RANGE STATUS 0
16
ALARM STATUS
Turns on when a protection function (OVP, OCP, OPP, OHP, REV, or UVP) is activated or
when an external alarm is applied. Open collector output by a photocoupler.
17
STATUS COM
STATUS signal common for pins 17 to 20.
